MSR Base Station Introduction and Measurement Challenges

WHY THIS WEBCAST IS IMPORTANT

Next generation base station (BS) transmitters, and receivers, will support wider bandwidths and include not only multiple carriers (MCs) of a single radio format, but also multiple formats in one transmitter path. As an example, GSM, W-CDMA and LTE MCs can be transmitted from a single multi-standard radio (MSR) base station unit simultaneously. Having BS support multiple formats in a cellular network is important for network operators to save both BS size and cost: MSR BSs are expected to realize a smooth and seamless network migration from the currently deployed 2/3G radio formats toward 3.9G (e.g. LTE) and even 4G (e.g. LTE-Advanced) technologies through certain periods of time. While it will be beneficial for the network service providers and mobile subscribers alike, applying MSR MC configurations may possibly introduce some unexpected BS RF performance degradations and finding an effective way to test MSR BS is an essential portion to ensuring the successful cellular network migration to MSR BS. Release 9 of the 3GPP specification includes a series of documents, TS37 series, which focuses on MSR BS conformance testing. These documents cover the MSR MC combinations of 3GPP FDD formats (e.g. LTE FDD, W-CDMA/HSPA and GSM/EDGE) and 3GPP TDD formats (LTE TDD and TD-SCDMA).
